[Python] How to Use Python to Control a Game?

I am trying to control a Vehicle in GTA5 using Python, by Using Scancodes.

I've already tried using Scancodes, and although I'm getting keypresses on Python Shell and all text based applications, GTA 5 refuses to take the input.

import ctypes
import time

for i in list(range(4)) [::-1]:
print(i+1)
time.sleep(1)

SendInput = ctypes.windll.user32.SendInput

W=0x11
S=0x1F
D=0x20
A=0x1E

# C struct redefinitions
PUL = ctypes.POINTER(ctypes.c_ulong)
class KeyBdInput(ctypes.Structure):
_fields_ = [("wVk", ctypes.c_ushort),
("wScan", ctypes.c_ushort),
("dwFlags", ctypes.c_ulong),
("time", ctypes.c_ulong),
("dwExtraInfo", PUL)]

class HardwareInput(ctypes.Structure):
_fields_ = [("uMsg", ctypes.c_ulong),
("wParamL", ctypes.c_short),
("wParamH", ctypes.c_ushort)]

class MouseInput(ctypes.Structure):
_fields_ = [("dx", ctypes.c_long),
("dy", ctypes.c_long),
("mouseData", ctypes.c_ulong),
("dwFlags", ctypes.c_ulong),
("time",ctypes.c_ulong),
("dwExtraInfo", PUL)]

class Input_I(ctypes.Union):
_fields_ = [("ki", KeyBdInput),
("mi", MouseInput),
("hi", HardwareInput)]

class Input(ctypes.Structure):
_fields_ = [("type", ctypes.c_ulong),
("ii", Input_I)]

# Actuals Functions

def PressKey(hexKeyCode):
extra = ctypes.c_ulong(0)
ii_ = Input_I()
ii_.ki = KeyBdInput( 0, hexKeyCode, 0x0008, 0, ctypes.pointer(extra) )
x = Input( ctypes.c_ulong(1), ii_ )
ctypes.windll.user32.SendInput(1, ctypes.pointer(x), ctypes.sizeof(x))

def ReleaseKey(hexKeyCode):
extra = ctypes.c_ulong(0)
ii_ = Input_I()
ii_.ki = KeyBdInput( 0, hexKeyCode, 0x0008 | 0x0002, 0, ctypes.pointer(extra) )
x = Input( ctypes.c_ulong(1), ii_ )
ctypes.windll.user32.SendInput(1, ctypes.pointer(x), ctypes.sizeof(x))


if __name__=='__main__':
while (True):
PressKey(0x11)
time.sleep(1)
ReleaseKey(0x11)
time.sleep(1)

The script needs to make a character move forward ingame by pressing 'W' automatically.

But I am unable to get it to work on GTA 5. However, the same code was used in this video :- https://www.youtube.com/watch?v=tWqbl9IUdCg&list=PLQVvvaa0QuDeETZEOy4VdocT7TOjfSA8a&index=3 and it worked.
